{% raw %} When writing component tests, prefer using global `screen` queries from Testing Library instead of container-specific queries or passing query functions as parameters. This approach keeps the test environment simple and consistent across the codebase. Instead of: ```typescript const { container } = render(); const input = container.querySelector('textarea')!; ``` Use: ```typescript render(); const input = screen.getByRole('textbox'); ``` Similarly, avoid passing query functions as parameters to test utilities when the global `screen` object can be used directly. This reduces complexity and follows the Testing Library's recommendation of using queries that resemble how users interact with your components. {% endraw %}
